WINDOW-FRAME CONSTRUCTION.

Application filed March 25, 1927. Serial No. 178,274.

This invention relates to window frames, and has especial .reference tothe sill construction.

The principal object of the present invention is to provide aweather'tight construction in a window frame between the sill and theside casings, to the end that air and water leakage will be prevented.and consequent rotting of the parts of the window frame.

The nature of the invention and its distinguishing features andadvantages will appear when the following specification is read inconnection with the'accompanying drawing, in which I Figure 1 is asectional view through the sill of a window frame embodying thestructural features of the present invention.

Fig. 2 is a sectional view taken on the line 22 of Fig. 1. H

Referring now more particularly to the drawings, it will be apparentthat there has been shown one of the side casings 10 of a window frameand sill 11. The side casing 10 comprises a front stile 12, a blind stop13, a jamb 14 and an inside stop 15. In the present instance in additionto the sill 11, there is shown a subsidiary sill 16.

The construction thus far described is one,

which has been found to be incomplete to exclude the elements of weathersuch as air and water from getting into the wall surrounding a windowframe, after the window frame has been exposed to the elements of theweather which cause the side casings and sill to shrink apart permittingair, water and dust to get into the wall. The water and dust causes theparts to rot in time, and in the winter time cold air makes the Wallcold and therefore the temperature in the interior of the house isdecreased. In accordance with thepresent invention the sill and sidecasings are cut to provide rabbeted joints between the sill and the sidecasings. The sill 11 is rabbeted as at 17 which provides a shoulder or.

raised portion 18 on the top face'of the sill; The lower end of eachfront stile 12 of the side casing is rabbeted as at 19 to provide afront depending shoulder or portion 20.

When the side casings 10 are associated with the sill 11, the frontdepending portion 20 .of

each front stile'12 will be fitted against the shoulder or raisedportion 18 of the sill 11,

beted joint between the sill 11 and the front stile 12.

It is to be understood that the rabbeted joints described may beprovided on either 7 one or two piece sills In the present in stance thesill is of two-piece construction. The lower end of the jamb 14 isconnected with the subsidiary sill 16 by a tongue and groove connection.tongue 21 which fits'in a groove22 in the front stile 12 to provide aweather tight joint at this point.

The principal feature of the present invention is to provide a rabbetedjoint between the sill, whether of one or two pieces,of a window frame,and the side casings, particularly between the front stiles respectivelyof the side casings and'the sill. Such construction has been found to beabsolutely necessary in window frames made of wood, to keep out theelements of weather and thereby prolong the life of the window frame.

I claim:

1 A window frame including a sill and side casing members out to providerabbeted joints between the sill and the side casings, and a second sillagainst'which the lower ends of said casing members abut.

2. A window frame includinga sill and side casing members, said sillrabbeted to provide a raised portion, and each of said side casingmembers rabbeted to provide a depending portion, the depending portionof each of the side casing members fitting against the raised. portionof the sill, and a second sill against which the lower rear faces ofsaid casing members abut. 3. A window frame includinga sill, and sidecasings each having afront stile, s'aid sill rabbeted to provide araised portion, and

each of said front stiles rabbeted to provide a depending portion, thedepending portion of each of the front stiles fitting against the raisedportion of the sill, and a second sill against which the lower ends ofsaid front stiles abut.
